Enabling Email Options for Salesforce for Outlook.


Make sure the Salesforce for Outlook icon is running in System Tray and it is red and not gray.  The Add Email button will never display if Salesforce for Outlook is not running in system Tray or it is in the gray state (not connected).

*** Please perform all the steps in the same order listed below and do not open Outlook or SFO during this process. Once you are done with Step 6 then go ahead and open Outlook and SFO and try to reproduce the issue ***



Once you have checked all the settings above, consider that it is possible that either the add-in was disabled by Outlook, the installation failed due to a security software or the user who installed the application did not have local administrator permission on the computer. 

Make sure the add-in is not listed under the Outlook Disabled items, look for


- Salesforce for Outlook Add to Salesforce Toolbar 
- Salesforce for Outlook Side Panel.
